Abstract

The concept of multi-microgrid (MMG) systems has gained significant research interest due to their enhanced reliability and efficiency compared to individual microgrids. This study uniquely conducts a bibliometric analysis of MMG systems, addressing a critical gap in existing literature, which predominantly focuses on microgrids and smart grids. Using the PRISMA technique, 2,011 documents from the SCOPUS database (2008–2024) were systematically reviewed and analyzed. Visualization tools like VOSviewer and Excel reveal that China and India lead MMG research, with significant contributions in energy management (EM) and control techniques. The study identifies "Energy" as the most-cited domain and highlights "Energies" as the longest-standing journal in the field. Keyword analysis associates MMG with "demand response" and "renewable energy," emphasizing the need to address uncertainties arising from increasing renewable energy integration. Additionally, the review identifies a focus on distributed generation optimization in MMG planning and frequency control using advanced strategies. By combining bibliometric analysis with a literature survey, this work provides a comprehensive and authoritative contribution, bridging gaps between existing microgrid and MMG studies. It offers valuable guidance for policymakers and researchers, advancing understanding and application of MMG systems to meet future energy challenges.
